"Bridgegroups" on branch srx

Hi, customers are asking me if bridgegroup functionality is available on the the srx devices like they are used to on the ssg's. I wrote something on the subject I think maybe some people here can benefit from:

The srx does not have bridgegroups, but it does support Ethernet switching options on the chassis interfaces. One or more VLAN configs can be configured to fulfill the exact same function as a bridgegroup. To use this solution first a VLAN should be defined:

vlans { dmz { vlan-id 100; l3-interface vlan.100; }}

Dmz is just a name for this vlanThe VLAN number is randomly chosen.The L3-interface will be used to configured the IP settings on.

Re: "Bridgegroups" on branch srx

One important item to note is that you cannot setup switching from one FPC to another. For example, I was trying to setup switching from ge-2/0/0 (fiber) to ge-0/0/0 and back to an EX switch using vlans. Advanced tech support caught this rather quickly, but tier 1 was unable to catch it.

just a note on this -- vlan l3 interfaces have an issue on the branch srxs, they don't see or process inbound ip-multicast, so this breaks vrrp and ospf on them, at least until 9.5r3 and 9.6r3 (supposedly)
